The riflescopes were marketed starting around 2003, I do not believe they lasted more than a year or two before they were discontinued.
I have a 3-9 and 3.5-10, and S&W refunded my purchase price on a defective 6-24. At the time (circa 2006) that I bought my scopes I think they were in the $80 to $130 price range from Cheaper Than Dirt, which was about 1/3 of the retail price. I do not know what company made the riflescopes, but they were made in Japan.
